TIPRL is an inhibitory regulator of protein phosphatase-2A (PP2A) (see PPP2CA; MIM 176915), PP4 (see PPP4C; MIM 602035), and PP6 (see PPP6C; MIM 612725) (McConnell et al., 2007 [PubMed 17384681]).[supplied by OMIM, Nov 2010]
Function:
May be a allosteric regulator of serine/threonine-protein phosphatase 2A (PP2A). Isoform 1 inhibits catalytic activity of the PP2A(D) core complex in vitro. The PP2A(C):TIPRL complex does not show phosphatase activity. May play a role in the regulation of ATM/ATR signaling pathway controlling DNA replication and repair.
Subunit:
Isoform 1 interacts with PPP2CA. Isoform 2 does notinteract with PPP2CA. Interacts with PPP2CB, PPP4C and PPP6C.Interacts with IGBP1; the interaction is dependent on PPP2CA.Associates with a protein phosphatase 2A PP2A(C):alpha-4 complex.
Subcellular Location:
Cytoplasm.
Similarity:
Belongs to the TIP41 family.
